Terminal Blocks - Barrier BlocksAs the use of industrial electrical components continues to increase, devices such as 5-1437667-3 have become a critical and necessary component when installing and operating high voltage equipment. This article will discuss the application fields and working principle behind these barrier blocks.Barrier blocks are a type of terminal block that is used to divide a circuit into multiple sections to help protect the components downstream. This is done by using barriers (sometimes referred to as breakers or separators) that provide a discrete electrical break at a specific point in the circuit, helping to protect the components on either side of the barrier block from accidental damage due to overloading or short circuits.The 5-1437667-3 has a rating of 10A per pole at 300V, making it perfect for use in manufacturing environments. These blocks can be used for both AC and DC applications, making them highly versatile for a wide range of applications. The blocks are capable of supporting stranded wire from 18 to 12 AWG (American Wire Gauge).The 5-1437667-3 also features a copper spring gate that helps to securely grip the stranded wire, avoiding accidental detachment of the wiring. The blocks also come with a molded polyester insulation that resists aging and helps protect against corrosion.The working principle behind barrier blocks is fairly simple. When the circuit is closed, electricity flows from the source through the individual barriers, allowing power to the downstream components. If one of those components becomes overloaded, it will trip its internal breaker, cutting off the flow of electricity and effectively isolating it from the rest of the circuit, thus protecting the downstream components from damage.In addition to protecting the components downstream, barrier blocks also provide a number of other benefits. They are highly cost-effective and easy to install (no need for specialized tools or technicians). They also serve to maximize space due to their compact design.Overall, the 5-1437667-3 is a versatile and reliable barrier block that is ideal for a wide range of industrial applications. It provides robust protection and is easy to use. The compact design of the block makes it a great option for an array of applications that need discrete breakers up to 10A at 300V.
